I make the same promise to myself every season that I won't charge anything!!
I bought my house in 2000 and back then I just did a couple track days a year. I work a full time job that pays the bills and I bartend two nights during the week to pay for racing costs. I also dedicate most of my tax returns to entry fees. I have a great girlfriend who not only supports my racing, but she also buys all the food and drinks for the weekend...
Racing definitely cuts into house maintenance time and money and with working two jobs it's tough to work on anything other than the bike and trailer. A new roof would be nice, but then I may have to miss a race
